Why do I think this is an important issue?
I understand that it can seem like a simple choice when faced with what looks like the same product priced at 1/3 of the cost of the original--money doesn't grow on trees, and we're all watching our budget these days.
Including the original artist who created the original design.
When a designer creates a product, say a nail-stamping plate, they spend hours designing the images, and spend their own money on production costs to do test runs, make corrections, and produce quality plates. They work hard and invest in a product that will allow them to put food on the table. When someone comes along and violates the copyright on the plate, they don't have to invest the time or the money--so they can make the plate at 1/3 of the cost. And now the designer doesn't get the return they earned on their investment, and they can't pay their bills. And, if they can't pay their bills, they'll probably stop designing plates, which means no more quality designs for us.
At the core of that, what it boils down to for me is this: the person violating the copyright is stealing, and I don't want to be a part of that.
I'm a blogger, and I'm a writer. I spend hours swatching, designing my nail art, perfecting my pictures, and writing my posts. In my other life, I write stories to entertain people. I certainly am not okay with someone stealing my posts or my pictures or my videos or my stories. If that's how I feel, then I have to treat others with the same respect.
The point of this page isn't to tell anyone what choice they should make, I'm not here to judge anyone but myself. But I do know that on the surface, buying a dupe (and other intellectual property theft) may feel like a victimless crime. So, I thought I'd explain my choice and present the other side of the issue, if it's useful to others trying to make their choice.
